What is the difference between an interstate CDL and an intrastate CDL?
• An intrastate CDL is one that is valid in Texas only. The requirements for these licenses are less strict than the federally controlled interstate licenses. Intrastate drivers are not required to speak English; not held to the same medical standards; and can obtain a license at the age of 18. Drivers with disabilities may also qualify at the intrastate level, as there are some exemptions available for those missing limbs or whose vision is impaired. • Interstate drivers are permitted to drive across state lines, but must be at least 21 to obtain a license.
